In response to a column I wrote two weeks ago (”Electoral Reform In Israel: Needed, But Not Likely,” Feb. 20), I received several calls and notes from Israeli activists advocating for Americanizing the system who said I was too pessimistic. They insisted that change was really in the air this time after the painfully inconclusive Israeli elections, noting that more and more political leaders recognized that the old system was simply dysfunctional and had to be improved.
